' IMPROVEMENT IN BELT-HOLE covE'Rs.

Specification forming part of Letters Patent No. 144,144, dated October28, 1873 application filed September 27, 1873.

To all whom it may concern:

Be it known that I, Town: P. Ronenns, of Taunton, in the county ofBristol and State of Massachusetts, have invented a new and usefulImprovement in Belt-Hole Cover, of which the following is aspecification:

Figure l is a top View of my improved belthole-cover. Fig. 2 is alongitudinal section of the same taken through the line as 00, Fig. 1;and Fig. 3 is a cross-section of the same taken through the line 3 y,Fig. 3.

My invention has for its object to furnish an improved cover forbelt-holes in floors, which shall be so formed as to prevent any rubbishthat may be upon the floor from dropping upon the belt and pulley belowthe floor, and thus injuring said belt, and which will enable the floorto be flooded in washing it, and in case of fire, without any danger ofthe water flowing through the belt-hole to the floor beneath. Theinvention consists in an improved belthole cover, formed of the threeparts constructed and arranged to operate in connection with each other,as hereinafter fully described.

The case, box, or stationary part of the cover is made in two parts, AB, which fit closely upon each other, and are secured together by boltsor rivets passing through the sides or upright plates a b of said case.a b are the bases or bottom plates of the case A B, and which aresecured to the floor by screws or bolts. The upright plates a 1) projectupward vertically, or at any desired angle, according to the directionof the belt, and are made in the form of segments of circles. a b arecurved or arched flanges formed upon the lower part of the inner sidesof the uprights a 1), near their edges. The inner edges of the curved orarched flanges a b correspond with and fit upon each other, where theyare se= cured in place by the projecting points a b, which interlockwith .eaeh other, as shown in Figs. 2 and 3. O is the upper or movablepart of the belt-cover, the base-plate c of which is curved upon the arcof a circle to fit and slide upon the arched flanges a b as a seat. Theside edges of the curved base 0 are kept in place by flanges formed uponthe curved edges of the uprights a N. In the middle part of thebase-plate c is formed a hole of sufiicient size for the belt to passthrough freely, and which is surrounded by an inclined flange, 0 makingthe opening hopper-shaped.

By this construction the belt can carry the upper part G of the coverwith it in its lateral movements, and the said part 0 will stand in anyposition into which it may be moved, preventing the belt from beingrubbed and chafed. Having thus described my invention, I claim as newand desire to secure by Letters Patent- An improved belt-hole cover,formed of the parts A a a a (0 ,13 b b b I), and O c" 0 said parts beingcombined to operate in connection with each other, substantially asherein shown and described.
